The International Symposium on Seawater Drag Reduction (ISSDR), held in Newport, RI, on 22-23 July 1998, focused on drag reduction methods applicable primarily in the seawater environment. The symposium was jointly sponsored by the Office of Naval Research (including ONR's European Office), the Naval Sea Systems Command, the Defense Advanced Research Projects Agency, the Naval Surface Warfare Center Carderock Division, the American Society of Mechanical Engineers and the Naval Undersea Warfare Center Newport Division. The call for ISSDR papers resulted in an overwhelming response from around the world. Accepted papers represent authors from 11 different countries and include contributions from the government sector, private industry, and academia. The resulting proceedings volume offers a comprehensive collection of the latest thinking on seawater drag reduction from leaders of the international drag reduction community. Papers are grouped in this volume in the following categories: * drag reduction - historical overview, * wall turbulence physics, * drag reduction physics * seawater physics * turbulent drag reduction methods including compliant coating, spanwise fluid motion and wall motion, polymer, microbubble, electromagnetic, and biology based methods. One of the fundamental advances in the study of turbulence over the last five decades has been the discovery that turbulence production and self-sustainment in a boundary layer are organized phenomena and not entirely random processes. A principal objective of this symposium and proceedings was to promote a closer coupling of these wall turbulence physics fundamentals to drag reduction methodologies, while also seeking to increase awareness of the challenges unique to seawater drag reduction, and encouraging wider and more extensive discussion in the drag reduction community of the potential applicability to seawater vehicles.
